TO ALL WHOM IT MAY CONCERN Be it known that we, W. RUSSELL and B. CARPENTER, of Northfield, in the county of Summit, and State of Ohio, and J. DRAKE, of Boston, Summitcounty, Ohio, have invented a new and useful Compound for Foot- Rot in Sheep; and hereby declare that the following is a full and complete description of the same, and the manner of using it in the treatment of that troublesome disease.

On examination of a sheeps foot it will be observed that there exists an issue or gland, lying directly under the skin, and extending upward along the middle of the leg, to the distance of from one to three inches, and then branching into numerous fine filaments. This gland or issue develops itself externally at the angle of the cleft of the foot, and rather deep back towards the heel. In a healthy foot it is of a whitish color, and somewhat rigid in texture, and from which issues a semi-liquid and transparent matter. In a diseased foot the gland is very much enlarged, highly inflamed, and sensitive, discharging freely a thick yellowish and caustic pus of highly offensive odor. This gland or issue is believed to be the origin and seat of the disease, the removal of which by dissection has been found to eradicate the ailment.

The surgical operation of removing this issue is as follows: An incision is made along in thedirection of the issue, which is then laid open, care being taken not to disturb or injure the numerous ligaments andinteguments by which the organ is surrounded, which, on being properly and fully exposed, is then dissected out. The incision may then be closed by any of the usual methods of dressing, and the compound hereinafter described applied for the purpose of cleansing and facilitating the healing of the wound. This compound consists of one-fourth of an ounce of sulphuric acid, one-half of an ounce of pine tar, one-eighth of an ounce of common salt, and one-eighth of an ounce of turpentine. These proportions may be varied in aslight degree without changing the nature of the compound. This compound can be applied to the wound with a soft piece of sponge,-or by other similar means. One application will generally be suificient, but it may be repeated.

What we claim as new, and desire to secure by Letters Patent,'is

The herein-described compound, applied as and for the purpose described.
